Disable pid check in apache startup on win32.

This is testing a theory that maybe we are not reliably computing
the pid the apache server is running as on win7, and we are getting
confused over whether the server is running. If this theory is correct,
we should either see the hangs go away, or get some sort of different errors
that might help to debug things.
